Kamarosusshv' starrne mamas-em A Application filed February 11',1926, Seria-1' No. szeoa an'd in Great Britain January 143.192'6.

This invention relates. to improvements in knives for use in flayii'ig cattle and the like purposes. a The usual type 'o'fslaught'erers skinning knife used for this purpose comprises a blade with a convex curved cutting edge and an approximately concave back. Great skill is required in using such knives to prevent raking and consequent damage to the hide.

One of the objects of the present invention is to prevent damage to thehides by spacing the tip of the knife away from the hide.

According to the present invention I provide a knife having a projection secured to the side of the blade tospace the blade away from the hide. The projection is preferably detachably secured. Since it is .the tip of the knife which damages thehide it is desirable to provide the projection on the blade in the neighbourhood of the tip so as-to leave the tip free to use but spaced away from the hide to prevent damage. The projection is suitablyof smooth contour preferably in the form of a domed stud. It

is preferablealso that the projection to'be detachable so that it can be removed when the knife requires to be sharpened.

The detachable smooth projection is'preferably secured in a hole in the blade of the knife near the tip e. g. by means of a screw. Two or more holes may be provided in the blade of the knife at different distances from the edge so that when the blade has worn with use, the stud may be moved into a more suitable hole.

The invention includes a knife having one 7 or more holes in the blade in the neighbourhood of the tip for securing a detachable projection to the tip. The invention also includes a domed stud drilled and tapped to be secured on to the blade of a knife by a screw. The studmay be drilled eccentrically so as to allow it to be moved away from or towards the edge of the blade by rotation if desired.

The accompanying drawings illustrate. a preferred form of my invention in'which:-- Figure 1 shows a plan view of a fiaying knife adapted to hold a stud.

Figure 2 shows an elevation of the knife in Figure 1 with the stud in position. Figure 3 shows a plan View of the knife shown in Figure 2.

Figure 4 shows a plan viewbf a blade with a modified form of stud.

The blade 1 of the knife hasah'and-IeQ. The cutting edge 3 of the blade curves back towards the -tip 4 and the blade is .provided with holes 5 and 6. When the knifeis 'n-ew' a domed stud? issecured in the hole 5 by the countersunk screw 8 lVhen it is 'necessaryto sharpen the knife the stud 7 can i be removed. 'l/Vhen-th-e knife has worn so that the hole 5 is too close to theedge' the stud may be placed in the hole 6. The .operator can however, improve the edge the aid of a steel without removal of the stud 7. I

In Figure 4 the stud7 is held by a screw 8 passing through it eccentrically. When the knife is new the studis placed so that it is close to the blade as possible. As'fthef knife wears it may be placed in fresh 'posi-' I a A fresh dome sn'ia ller,

tions in the same hole, further from the edge of the blade. than the first may be used in the hole '6.

The invent-ion is not limited to 'the'preferred construction shown above; For left handedworkers the stud may be placed'on the other side of theblade. Or studs may be placed on both sides although I prefer to keep one side unobstructed.

The stud may take the form of a round headed screw with a shank but I prefer to have a drilled stud and a screw secured from the otherside of the blade. I-The'head' of the securing screw 8 on the drawings may be recessed for a screw-driver or, suitably formed to be fastened withthe fingers.
